Question

我正在尝试使用php脚本编辑sql表中的记录。我可以加载一个表单，让我编辑文本，但是当我按下提交时它不会保存新的记录名称。它只是将我重定向到没有编辑的表格页面。

（包括DB）

PHP doc说：

参数标识符。对于使用命名占位符的预准备语句，这将是:name形式的参数名称。对于使用问号占位符的预准备语句，这将是参数的1索引位置。

在您的代码中，您使用"s"作为bindParam的参数！

<?php
function renderForm($ArtistName = '', $error = '', $ArtistID = '')
{
    //
}


if (isset($_GET['submit'])){
    if (isset($_POST['ArtistID'])){
        if (is_numeric($_GET['ArtistID'])){
            $ArtistID = $_GET['ArtistID'];
            $ArtistName = htmlentities($_POST['ArtistName'], ENT_QUOTES);
            if ($ArtistName == ''){
                $error = 'ERROR: Please fill in all required fields!';
                renderForm($ArtistName, $error, $ArtistID);
            }else{
                if ($stmt = $conn->prepare("UPDATE Artists SET ArtistName = ? WHERE ArtistID=?")){
                    $stmt->bind_param(1, $ArtistName);
                    $stmt->bind_param(2, $ArtistID, PDO::PARAM_INT);
                    $stmt->execute();
                    $stmt->close();
                }else{
                    echo "ERROR: could not prepare SQL statement.";
                }
            }
        }
    }
}
?>
